1 Claim.

The invention relates to a heated roll, and more particularly to oilheating means for mangle rolls used in ironing machines or other likemachinery.

The primary object of the invention is the a provision of means of thischaracter, wherein an ironing roll will be heated by the use of oil orother suitable liquid which will give the required or necessary heatwithout boiling or evaporating.

Another object of the invention is the provision '10 of means of thischaracter, wherein oil or other suitable liquid is introduced into oneend of the heated ironing roll and exhausting it at the other oropposite end of such roll and plenum or vacuum being employed sufficientto cause the oil 'or'other 3 liquid to flow at the necessary'speedthrough the roll, and a conduit being provided to carry the oil to themiddle of such roll with branches or perforated pipes associatedtherewith to distribute the oil or other liquid equally in oppositedirections 13 or to both sides of the median of the roll.

A further object of the invention is the provision of means of thischaracter, wherein the oil or other liquid in its distribution withinthe roll will be maintained at a uniform temperature throughout thelength of said roll, the oil or other liquid being distributed in bothdirections and also exhausted in both directions from the median of theroll and the distributing medium being stationary while the roll rotatesso that a thorough agitation of the oil or other liquid is had.

A still further object of the invention is the provision of means ofthis character, which is comparatively simple in construction,thoroughly reliable and eflicient in its purpose, strong, dur- 1 3 ableand inexpensive to manufacture and install.

With these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in 4') the accompanyingdrawing which discloses the preferred embodiment of the invention, andpointed out in the claim hereunto appended.

In the accompanying drawing:

Figure l is an elevation of the means construct- 4 ed in accordance withthe invention and showing the heated ironing roll in verticallongitudinal section.

Figure 2 is a fragmentary sectional view on the line 2-2 of Figure 1,looking in the direction all of the arrows.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail A designates generally the heatedironing roll which is in the form of a cylinder having fitted inopposite extremities end heads 11 and 12, these being pro-' vided withcentral hubs 13 journaled in side uprights 14, of the frame of amachine, for example an ironing machine. The roll A is rotated in anysuitable manner from power furnished the machine. Concentricallydisposed about the roll A is a series of closely arranged presser rolls15,

these being suitably journaled in the uprights 14 of the frame to coactwith the outer face of the mangle A during the ironing operation or whenlinen or other materials are mangled, the linen or materials being fedbetween the same from a stand or other support, as shown in Figure 2 ofthe drawing.

Arranged centrally within the-cylinderlo is a conduit 16, which isextended reversely through the journals or hubs 13 of the end heads 11and 12, these being provided with stufling boxes 17 for the conduit.Spaced from the conduit 16 and arranged close to the inner face of thecylinder 10 and coextensive therewith and parallel thereto areperforated distributing pipes 18 and 19, re-

spectively, the pipe 18 being connected with the conduit 16 by thebranch 20, while the pipe 19 is connected to this conduit by the branch21,

these branches being on opposite sides of the median of the cylinder 10.The pipe 18 constitutes an oil or other suitable liquid distributor andthe same is provided with a row of perforations 22 serving as outletsfor heated oil or other liquid from the conduit 16 into the cylinder 10.The pipe 19 constitutes an exhaust from the cylinder 10 for the oil orother liquid and the same is provided with a row of'perforations 23serving as outlets 9 therefrom. The conduit 16 between the branches 20and 21 is suitably closed preferably by a plug 24 so as to divide thisconduit into an inlet stretch 25 for the oil or other liquid and anoutlet stretch 26 for the exhaust of the oil or other liquid. The Qpipes 18 and 19 are held rigidly spaced by brackets 27, which arecarried by the conduit 16, while the outer ends of the pipes are fittedwith removable caps 28 for permitting the cleaning thereof. Located at asuitable point is an oil or other liquid heater 29 from which extends afeed tube 30 which is connected with the conduit 16 at the outer end ofthe inlet stretch 25 thereof so as to feed heated oil or other liquidthereto, and arm5 ranged within this tube 30 is a suitable themestat 31,which is also associated with the burner tube 32 so as to control theburner not shown of the heater 29, as will be obvious. Also this tube 30carries a suitable gauge or thermometer 33 2 so that the oil or liquidcondition can be determined.

Arranged spaced from the heater 29 is a suitable pump 34 which at itsperiphery has a lead 35 to the heater and this lead carries a strainer36 and a hand operated valve 37, while extended from the center of saidpump 34 is a lead 38, the latter being connected with the outlet stretch26 of the conduit 16. The lead 38 close to the pump 34 has theconnection 39 with an oil or other liquid supply tank 40, the connection39 being provided with a hand operated valve 41, while the lead 38 hasthe connection 42 with anexpansion tank 43 provided with a sight tube 44and the connection being provided with a gauge 45. The lead 38 is fittedwith a hand operated valve 46.

Opening through conduit 16 and oppositely extending from and inalignment with the branch 21 is an air vent outlet 47, which extendsthrough the outlet stretch 26 and also through the lead 38 to withoutthe cylinder 10 and the outside end of this vent tube 47 is fitted intoa valved cook 48.

The burner tube 32 is fitted with a hand operated valve 49, while thelead 38 carries a mometer 50.

In the operation of the roll A it will be apparent that oil or othersuitable liquid which will give the required degree of heat withoutboiling or evaporating is conveyed from the heater 29 through feed tube30 into the inlet stretch 25 of the conduit 16 whence it is distributedthrough pipe 18 into the cylinder 10 for the heating of the roll A andany gases or air formed therein due to agitation of the oil or liquidtherein on distribution thereof will be drawn on through vent outlet 47.on the opening of its cook 48 outside of the cylinder 10. The pipe 18will carry the oil or liquid to the middle of the roll A anddistribution will be had throughout the cylinder 10. Thus it will beseen that the heated oil or liquid enters the roll at one end and isexhausted therefrom at its therother end by the pipe 19, these pipes 18and 19 being extended in both directions so that an equal distributionand exhaust is maintained and a uniform temperature had all along thelength of said mangle, and the rotation of the cylinder 10 causes theagitation of the oil or liquid. The oil or liquid is supplied heated tothe cylinder 10 under a plenum or a vacuum, and the temperature of suchliquid or oil being regulated to meet the requirements of the work to bedone by the roll A.

In the operation of the roll A the oil or liquid is caused to flow inthe cylinder 10 at the necessary speed under the employment of plenum orvacuum.

From the foregoing it is thought that the construction and manner ofoperation of the invention will beclearly understood and therefore a.more extended explanation has been omitted.

It is to be understood that changes, variations and modification may bemade in the invention, without departing from the spirit or sacrificingany of its advantages and as fall properly within the scope of theappended claim.

What is claimed is:

In fluid heated rolls. a cylinder, end heads fitting the cylinder andeach having a central hub, uprights having the hubs journaled therein,a. conduit arranged centrally in the cylinder and extending reverselythrough the hubs, distributing pipes arranged close to the inner wall ofthe cylinder and parallel with the conduit, branches connected close toeach other with the conduit midway of the cylinder and with thedistributing pipes, a closing plug in the conduit between the branches,a heated fluid supply connected to one end of the conduit, an exhaustconnected to the other end of said conduit, and a valved vent tubeleading from within the-cylinder through a portion of the conduit towithout said cylinder.
